IMPROVEMENT IN HARROWS.

Specification forming part of Letters Patent No. 150,662, dated May 5,1874 application tiled March 7, 1874.

To all whom it may concern:

Be it known that I,- FERDINAND Pos'r, of

- Moulton, in the county of Appanoose and State of Iowa, have invented anew and Improved Harrow, called the Universal Rever' sible Harrow, ofwhich thefollowing is a specification:

Figure 1 of the drawings is a representa tion of a plan view of myharrow. Fi g. 2 is a side view of the same.

The nature of my invention consists in a diagonal brace, which isapplied between two articulating harrow-sections, and which will preventthe sections from receiving independent endwise movements withoutinterfering with their flexibility, in combination with the bars whichcouple together the harrowsections in front and in rear, as draft-bars,to one or the other of which the clevis or shackle is adjustablyapplied, as will behereinafter explained.

The following is a description of my invention:

In the annexed drawings, A A designate apart, by means of couplingbars GU, which are attached, by means of eyebolts c, to the cross-bars cc,which bolts allow free articulation of the sections, so that they willaccommodate themselves to inequalities of the surface passed over. Thesebars G U have attached to them the shackle or clevis loop f, to whichthe. horses are hitched, which loop is removable and adjustable to oneor the.

other of a number of perforations, 'i, through the bars. I am thusenabled to draw the harrow from any point along theline of eithercoupling-bars, according as it may be desired to harrow finer orcoarser. To keep the two sections A A at a given distance apart, andprevent one section moving in advance of the other, I employ a diagonalcoupling-brace, D,

The diagonal brace D, jointed to the sections A A, in combination withthe front and rear couplingbars O G, as herein described.
